Detroit Medicare Basics for the Initial Enrollment Period

# Turning 65 in Detroit? Don't Miss Your 7-Month Medicare…

DETROIT — If you're approaching your 65th birthday, the calendar is already working for you — and against you. Medicare gives most people a seven-month Initial Enrollment Period to sign up, and missing it can mean gaps in coverage and late penalties that stick around for life. Getting the timing right is the single most important first step.

The 7-month window, explained

Your Initial Enrollment Period (IEP) is built around your 65th birthday month. It starts three months before that month, includes it, and ends three months after — seven months in total.

If you enroll during those first three months, your Medicare coverage can begin on the first day of your birthday month. If you wait until your birthday month or later, coverage can be delayed by up to a month. That's why signing up early in the window is usually the calmer choice.

You sign up for Original Medicare (Parts A and B) through the Social Security Administration, either online at ssa.gov, by phone, or at a local office.

When you might be enrolled automatically

Already collecting Social Security benefits before you turn 65? In most cases, you'll be automatically enrolled in Part A and Part B, and your red, white, and blue Medicare card will arrive in the mail about three months before your birthday.

If you're not yet drawing Social Security, enrollment is not automatic. You'll need to sign yourself up during your IEP.

Still working at 65? Read this carefully

Many Detroiters keep working past 65, often with employer health coverage through an auto plant, hospital system, school district, or small business. If that's you, the rules shift a bit.

If your employer has 20 or more employees, you can usually delay Part B without a penalty and pick it up later through a Special Enrollment Period after your job or job-based coverage ends. If your employer has fewer than 20 employees, Medicare typically becomes the primary payer at 65, and delaying could leave you with coverage gaps.

Before making any decision, talk to your employer's benefits office and call your local State Health Insurance Assistance Program (SHIP). In Michigan, that's the MMAP (Medicare/Medicaid Assistance Program), which offers free, unbiased counseling.

The pieces you'll choose between

Once you have Part A and Part B, you'll decide how to round out your coverage. The main paths:

• Original Medicare (Parts A and B), often paired with a stand-alone Part D drug plan and, for some people, a Medigap (supplement) policy.
• Medicare Advantage (Part C), which bundles Parts A and B — and usually Part D — through a private plan approved by Medicare.

Detroit is in Wayne County, where multiple carriers offer Advantage and Part D plans. The number of options can feel overwhelming, but the county-level menu is broad enough that most people can find a fit. Compare on medicare.gov's Plan Finder, which lets you enter your prescriptions and preferred pharmacies.

What's new for 2027

A few program-level numbers to keep in mind as you plan:

• Part D has an out-of-pocket cap of $2,100 in 2026. Once you hit that ceiling on covered drugs, you pay $0 for the rest of the calendar year.
• The maximum Part D deductible is $615 in 2026 and $700 in 2027.
• The old "donut hole" coverage gap is gone as of 2025 — Part D now has three phases instead of four.
• The Medicare Prescription Payment Plan lets you spread drug costs across monthly payments over the year instead of paying big amounts at the pharmacy counter.
• IRMAA surcharges — extra amounts higher earners pay for Parts B and D — start above $109,000 in income for a single filer in 2026.

After you enroll: the dates to remember

Once you're in Medicare, two windows come up every year:

• Annual Enrollment Period: October 15 – December 7. You can join, switch, or drop a Medicare Advantage or Part D plan.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in an Advantage plan, you can switch to a different Advantage plan or return to Original Medicare (and add a Part D plan).

Mark these on your calendar. Even if your coverage is working well, it's smart to review it each fall, because plans change their formularies, provider networks, and costs year to year.
